By adding a trolley system, the Xpanda Rollerguard becomes a mobile pedestrian barrier. It has many beneficial applications in that it is not restricted by being fixed to a structure, although it can, if required. The Rollerguard trolley system is lightweight and allows for complete mobility and versatility. It can be moved to cordon off areas, or stored when not required. It can be joined together with other Rollerguards and have different lockable configurations. Common uses include the temporary securing of areas in Malls, construction sites and areas where temporary cordons are required to be provided.
